METAL HOOP. APPLICATION- FILED Angie, 1904.

hereby declare clear, and exact description of the invention, such as will enableothers skilled in the art to through JAMES E. WRIGHT, OF WEST BAY OITY MICHIGAN, ASSIGNOR O KELTON, BAY GITY, MICHIGAN.

ME AL noon.

T 0 all whom it may co'ricer'nf Be it known that I, Janus E. WRIGHT, a citizen of the United States, residin at-West Bay City, in the county of Bay an j State of:

Michigan, have invented certain new and useful Improvements inMetal Hoops; and 'I do the following to be a full,

which it .appertains to make and use the same. p

bead'metal hoops, one object being the provision of a hoop having a 'reinforced driving edge, which Wlll not-require the amount of metal heretofore necessary in making closed bead hoops. p I

W'ith these and other objects in view,

which will appear later in the specification,- the invention consists in certain novel fea-' tures and combinations of parts together with their equivalents, such as will be more fully described hereinafter and particularly pointed outin the claims.

In the accompanying drawings, Figure 1 is a view of a barrel equipped with a hoop constructed after my invention, partly broken away to better disclose the structure,

Fig. 2 is a perspective view of a-portion of a barrel stave showing the hoop in cross sec-' tion, and Fig. 3 is a cross sectional view a hoop showing how the bead may be closed in some instances.

As is clearly indicated, the hoop consists of a flat metal band (1), the upper edge of which is formed with an outwardly curved or arched line.

downwardly m an approxlmately straight The free edge (3) 0f the bead may be turned very slightly inwardly for the purpose equi ped with these hoo s, though t 's inmore, y forming an open bead ascontradisof prevent an exposure of the raw edge of the bead, w tage in handling or transporting-rose ta'cles when ressureLis applied thereto; Further- S pecification of Letters Patent.

Obviously, if the head is to be closed "during the driving operation, 'the lap edends of the hoop can be nested into eac other, ,just as though the head was to remain open.

Nor is the bearing surface of the hoop band reduced when the open bead the bead being closed withdrawing upon the band. While these hoo s are more particularly designed as bi ge hoops, they may also be used on the chine of a barrel. This hoop can be manufactured either in straight or roll lengths, which may be kept in stock and as much sold from the stock as is desired.
